From the surface of Necron Red II, the motions of Ichaya appear very different from that of our own moon. Ichaya rises in the north, sets in the south, and rises again in just 11 hours. | From the surface of Necron Red II, the motions of Ichaya appear very different from that of our own moon.

Because Ichaya's orbit is below synchronous altitude, the tidal forces from the planet Necron Red II are gradually lowering its orbit. In about 50 million years it will either crash into Necron Red II’s surface or break up into a ring structure around the planet. | Because Ichaya's orbit is below synchronous altitude, the tidal forces from the planet Necron Red II are gradually lowering its orbit.

It is not well understood how or when Necron Red II came to capture its moon. Ichaya has a very circular orbit, very near the polar equator, which is very unusual in itself for captured objects. Ichaya's unstable orbit would seem to point towards a relatively recent capture. There is no known mechanism for | It is not well understood how or when Necron Red II came to capture its moon. Ichaya has a very circular orbit, very near the polar equator, which is very unusual in itself for captured objects. Ichaya's unstable orbit would seem to point towards a relatively recent capture. There is no known mechanism for an airless Necron Red II to capture a lone stellar object, so it is likely that a third body was involved — however, asteroids or other planetary bodies in the Necron System are rare. | ||

The current understanding of planetary habitability—the ability of a world to develop and sustain life — favors planets that have liquid water on their surface. This requires that the orbit of a planet lie within a habitable zone. Necron Red II orbits half an astronomical unit beyond this zone and this, along with the planet's thin atmosphere, causes water to | The current understanding of planetary habitability—the ability of a world to develop and sustain life — favors planets that have liquid water on their surface. This requires that the orbit of a planet lie within a habitable zone. Necron Red II orbits half an astronomical unit beyond this zone and this, along with the planet's thin atmosphere, causes water to freeze on its surface. The past flow of liquid water, however, demonstrates the planet's potential for habitability. Recent evidence has suggested that any water on the surface would have been too salty and acidic to support native life. However, we see the tenaciousness of biological life everywhere we look on Necron Red II. Through either biological evolution or through adapting alternate biological processes, the carbon based lifeforms on Necron Red II have thrived despite the harsh conditions that prevail here. | ||
The lack of a magnetosphere and extremely thin atmosphere of Necron Red II are an even greater challenge: the planet has little heat transfer across its surface, poor insulation against radioactive bombardment and the ionizing effects of Necron Red's harsh solar wind. This along with insufficient atmospheric pressure to retain water in a liquid form (water instead sublimates to a gaseous state) places the odds of native life flourishing here astronomical. Necron Red II is also nearly, or perhaps totally, geologically dead; the end of volcanic activity has stopped the recycling of chemicals and minerals between the surface and interior of the planet. | The lack of a magnetosphere and extremely thin atmosphere of Necron Red II are an even greater challenge: the planet has little heat transfer across its surface, poor insulation against radioactive bombardment and the ionizing effects of Necron Red's harsh solar wind.
